    Abstract: A first virtual machine executing in a first computer server is replicated to a second virtual machine executing in a second computer server, which is connected to the first computer server over a network. Virtual disks of the first virtual machine are transmitted to the second server, where each transmitted virtual disk corresponds to one of the virtual disks of the second virtual machine, the virtual disks of the first virtual machine having a format different from the format of the virtual disks of the second virtual machine. A plurality of updates to the virtual disks of the first virtual machine is captured, and contiguous data blocks from the virtual disks of the first virtual machine that are subject to the captured updates are identified. The identified contiguous data blocks are then transmitted to the second server for storage in the virtual disks of the second virtual machine.

    Abstract translation: 在第一计算机服务器中执行的第一虚拟机被复制到在通过网络连接到第一计算机服务器的第二计算机服务器中执行的第二虚拟机。 将第一虚拟机的虚拟磁盘发送到第二服务器,其中每个发送的虚拟磁盘对应于第二虚拟机的虚拟磁盘之一,第一虚拟机的虚拟磁盘的格式与虚拟磁盘的格式不同 第二个虚拟机的磁盘。 捕获对第一虚拟机的虚拟磁盘的多个更新,并且识别来自被捕获的更新的第一虚拟机的虚拟磁盘的连续的数据块。 然后将所识别的连续数据块发送到第二服务器以存储在第二虚拟机的虚拟磁盘中。
